that with them. in, and apologizing for them as lie does, Mr. Clark should have selected this as a model of what the report of a scientific commission ought to be and sufficient of itself to forever fix the value of the scientific expert in the settlement of government disputes? As I have already intimated, no one appreciates more highly than I the great work done by Dr. Jordan and his associates in the study of the natural history of the seal. May not the work of the two commissions, as bearing on the problem of the fur-seal industry be summed up about as follows?—The report of the American members of the first commission related facts, declared causes, and proposed remedies. The American case at the Paris arbitration rested on these. As almost universally happens, arbitration resulted in compromise, unsatisfactory to both parties, and, as has since turned out, decidedly unfavorable to one. The commission of 1897 has made a joint report of considerable length and much importance, in which the "facts, causes, and remedies" of the report of 1892 are in a sense confirmed, but with a number of concessions that do not strengthen the American contention regarding pelagic sealing, the justice of which seems to be admitted by Mr. Clark. But the practical question is. What has been the effect of either or both of these commissions upon the fur-seal industry? It would be unkind to press this question upon one who characterizes the work of the first commission as above quoted, and who speaks of the second as having, after being in joint session one week, "concluded its labors, reaching a full and satisfactory agreement." If he really wishes to know what progress is being made under such an agreeable state of affairs, let him inquire of the International Joint Commission, which is endeavoring to arrange all outstanding differences between this country and Canada.

CAUSES AND PREVENTION OF INSANITY.

By SMITH BAKER, M. D.

IT is being found out that cases of insanity may of themselves fall naturally into two classes: the first comprising those who get well, and the second those who do not. To the first class belong the deliriums of fevers and other like diseases, and also certain acute manias and melancholias and the so-called generalized insanities. In the second class are included the insanities which last indefinitely, or, if seemingly cured, which, in the proportion of from twelve to fourteen per cent, come back again one or more times, and finally do not recover. Says Regis: "Out of all forms of mental alienation or insanity only the generalized types—i. e., mania and melancholia—are curable. The systematized insanities are essentially chronic and
